loop a list in java code example

Example 1: java loop through arraylist

ArrayList<String> namesList = new ArrayList<String>(Arrays.asList( "alex", "brian", "charles") );
         
for(String name : namesList)
{
    System.out.println(name);
}

Example 2: java iterate over list

for (int i = 0; i < crunchifyList.size(); i++) {
            System.out.println(crunchifyList.get(i));
        }

Example 3: iterate through an arraylist java

// will iterate through each index of the array list
// using the size of the array list as the max.
// (the last index is the size of the array list - 1)

for (int i = 0; i < myArrayList.size(); i++) {
  
  System.out.println(myArrayList.get(i));
  // will print each index as it loops
}

Example 4: iterate list in java

Iterator itr=list.iterator();
while(itr.hasNext)
{
 system.out.println(itr.next); 
}
